Grid board dice game
Grid board dice game: Teachers’ notes
This game works well with 3 to 6 children.
Equipment


Number grid from 1 to 70
3 ordinary dice
Pupils take turns to roll 3 dice. The objective is to combine the numbers on the
dice by adding, subtracting, doubling or halving. Pupils may use any of these in
any order; repeat operations if wanted....but all 3 numbers must be used just
once.
 The dice roller has first attempt to form sum to match one of the board
numbers. This number is then “captured” by covering with a counter.
Other players may then try to “capture” a different number. After all
have tried or “passed”, another player rolls the dice for a new round
and the game continues as before.
 The winner is the player with most captured numbers. Alternatively (for
more-able) the winner is player whose sum of all captured numbers is
greatest.....or perhaps least?
Fluency and reasoning (as well as creativity in solving problems) are the main
principles behind this activity. So all three aims of the National Curriculum are
addressed.
There is also a strong element of mental calculation in this work – an area that
may often be over-looked or difficult to fit in.
Introducing an element of competition into the activity will generate still more
interest. The game will fit part of a lesson – perhaps as a reward – or can be
used at a problematic time: just before lunch, last on a Friday.
Plenary opportunities are available away from the game itself:
 Are all numbers possible to make?
 Could we use a bigger board?
 Which numbers are possible in different ways?
Variation



As pupils are more confident / able to use multiply & divide operations
allow use of these.
Use a bigger board with more numbers....or perhaps a smaller board.
As with any game, it is the mathematics which counts. Rules can be
changed to suit different needs of pupils...as long as all are clear about
these before we start.
I would often say to teachers on training day that the game is your
slave; you are not its slave.
Differentiation is possible:
 Lower-attaining children might use only add, subtract, double and half.
 Higher attaining pupils might bring other operations – square root,
factorial, etc
 One pupil enjoyed it so much she played solo, trying to find every
number on the board, throwing 3 dice and each time trying to form
another new number.
